Tools for woodworking - Safety requirements - Part 1: Milling tools, circular saw blades
This European Standard specifies all hazards arising from the use of tools for woodworking machines, and describes the methods for the elimination or reduction of these hazards by tool design and by the provision of information. This European Standard deals with milling tools (bore mounted, shank mounted), integrated tools and circular saw blades.
This European Standard does not cover any hazard related to the strength of shank of shank mounted milling tools. The hazards are listed in Clause 4. This European Standard does not apply to boring bits, eccentric single router cutters, cutters with cutting circle less than 16 mm and to tools used in rotary knife lathes and copying lathes where the hazard of ejection and contact with the tool is always prevented by a system of fixed guards and/or movable guards interlocked with guard-locking and/or self-closing guards.
Maschinen-Werkzeuge für Holzbearbeitung - Sicherheitstechnische Anforderungen - Teil 1: Fräs- und Hobelwerkzeuge, Kreissägeblätter
Diese Europäische Norm gilt für alle Gefährdungen, die sich aus der Verwendung von Werkzeugen für Holzbearbei¬tungsmaschinen ergeben, und legt die Verfahren für die Beseitigung oder Verringerung dieser Gefährdungen durch die Gestaltung des Werkzeuges und durch die Bereitstellung von Informationen fest. Diese Europäische Norm behandelt Fräswerkzeuge (mit Bohrung, mit Schaft), integrierte Werkzeuge und Kreissägeblätter.
Diese Europäische Norm bezieht die Gefährdungen in Verbindung mit der Schaftfestigkeit von Fräswerkzeugen mit Schaft nicht ein. Die Gefährdungen sind in Abschnitt 4 aufgeführt. Diese Europäische Norm gilt nicht für Bohrer, einschneidige Schaftfräser für exzentrische Spannung, Fräser mit einem Schneidenkreis von weniger als 16 mm und für Werkzeuge in Drehmaschinen mit rotierendem Werkzeug und Kopierdrehmaschinen, bei denen einer Gefährdung durch Herausschleudern oder durch Kontakt mit dem Werkzeug stets durch ein System von feststehenden und/oder beweglichen Schutzvorrichtungen mit Zuhaltung und/oder mit selbstschließenden Schutzvorrichtungen vorgebeugt wird.
Outils pour le travail du bois - Prescriptions de sécurité - Partie 1: Outils de fraisage, lames de scies circulaires
La présente Norme européenne spécifie tous les phénomènes dangereux résultant de l’utilisation des outils pour machines à bois et décrit des méthodes de conception des outils ainsi que des procédures d’information permettant d'éliminer ou de réduire ces phénomènes dangereux. La présente Norme européenne traite des outils de fraisage (à trou, à queue et à broche), des outils intégrés et des lames de scies circulaires.
La présente Norme européenne ne couvre pas les phénomènes dangereux relatifs à la résistance de la queue des outils de fraisage à queue. La liste des phénomènes dangereux est donnée à l'article 4. La présente Norme européenne ne s'applique pas aux mèches à percer, aux fraises pour défonceuses à lame unique pour utilisation sur mandrin excentrique, aux fraises ayant un diamètre de coupe inférieur à 16 mm ni aux outils utilisés sur des tours rotatifs et des tours à copier où le risque de projection et de contact avec l'outil est toujours empêché par un système de protecteurs fixes et/ou mobiles interverrouillés et/ou des protecteurs à fermeture automatique.
Orodja za obdelavo lesa - Varnostne zahteve - 1. del: Rezkalno orodje, listi krožnih žag
Ta evropski standard določa vse nevarnosti, ki izhajajo iz uporabe orodij za obdelavo lesa, in opisuje metode za zmanjšanje ali odpravo teh nevarnosti z zasnovo orodja in zagotavljanjem informacij. Ta evropski standard obravnava frezala (pritrjena v izvrtino, pritrjena na držalo), integrirana orodja in krožne žage. Ta evropski standard ne obravnava nobene nevarnosti, povezane z močjo držala pri frezalih, pritrjenih na držalo. Nevarnosti so navedene v točki 4. Ta evropski standard se ne uporablja za vrtalne glave, ekscentrične enojne nadrezkarje, rezkalnike s krogom rezkanja, manjšim od 16 mm, orodja, ki se uporabljajo za stružnice z rotacijskim nožem in kopirne stružnice, pri katerih se nevarnost izmeta in stika z orodjem vedno preprečuje s sistemom fiksnih varoval in/ali premičnih varoval, povezanih z blokado varovanja in/ali samozapornimi varovali.
